SporTrak Color GPS Mapping Receiver
Frequently Asked Questions
How often do I need to initialize the SporTrak?
Initializing the SporTrak decreases the time it takes to get a position fix during
cold start. What is meant by a cold start is that the SporTrak has no reference
to use as a guide to tell it what satellites should be overhead. Without a
reference to start with, the SporTrak will have to “search the sky” trying to find
any satellite that may be in “view.” This takes time and can increase the time it
takes to get its first position fix. (Can take 10 minutes in severe conditions.)
So where does this reference come from? Under normal operating conditions,
the last position fix computed before the SporTrak was turned off is stored into
memory and will be used as the reference the next time the SporTrak is turned
on. However, if you cleared the memory (see Clearing Memory - All in the
Reference Chapter) this stored reference point is removed from memory and
you probably will want to initialize the receiver again. Also, if you travel with
your SporTrak for more than 500 miles with it turned off, it will still have the
reference point but it may be too inaccurate to be useful and again, you may
want to initialize the SporTrak.
Waypoints/Database
What waypoints come preloaded on my SporTrak’s database?
The Database contains cities, highways, airports, waterways and national parks.
Can I delete preloaded waypoints that I don’t use?
No. Waypoints that are preloaded into the SporTrak will always be available,
even when all of the SporTrak’s memory has been cleared.
Routes
What is a backtrack route?
A backtrack route allows you to “retrace” your steps. As you are moving, the
SporTrak automatically creates and stores hidden waypoints into memory.
These waypoints are the ones that the SporTrak will use to retrace your steps.
When you create a backtrack route, the SporTrak converts these hidden
waypoints into User Waypoints.
How do I know which route is active?
Access the route menu by pressing the
[MENU] button and select the
option Routes. The route menu lists all of the routes in memory with the
active route displayed in bold characters.
